Chrome NewTab Incompatible (ex.Workflowy styles)

Various productivity websites have companioning NewTab extensions. These websites have custom created Styles hosted here, on this website.However, these Styles are not compatible with their respective website if this website is launched as a NewTab homepage in Chrome.

Why don't they work?I've tried adding "chrome://newtab/" to the "url applies to" option within the Edit section of Stylish.-Doesn't work

Example images show a checkmark icon Style used next to an item to represent completion.

Specify the actual URL which you can see in devtools console (F12 key or Ctrl-Shift-I) after pasting location.href and pressing the Enter key. Or simply click "write new style" in the popup and it should use the actual URL.
